In particular the invention relates to a container of the foregoing type which is particularly suitable as a merchandising pack for tape cassettes.

The use of magnetic tape cassettes for recorded music and the like can sometimes pose a problem of storage and access to an owner if several cassettes are owned. Each cassette is usually sold in a merchandise container in the form of a box with a hinged or removable lid, and after use the cassette is usually returned to its box and in order to protect it from damage and the entrance'of dust and dirt into the cassette. As there is no convenient way for securing the boxes together a collection of cassette boxes may easily become jumbled and untidy creating a problem of finding a particular cassette when it is desired. Moreover, the hinged lids of some of the jumbled boxes may fall open permitting the ingress of dust and other degrading materials to the cassettes within.

SUMMARY OF THE INVENTION The present invention avoids the previously discussed problems by providing an attractive merchandise container for the cassette, which after purchase can be releasably connected to other, identical containers to form a connected file assembly for cassette storage.

More particularly this invention provides a container for magnetic tape cassettes, which may be releasably secured to identical, other containers to build up a connected file assembly for the storage of cassettes.

This desirable result is achieved by providing a container including a housing having a drawer slidably mounted for motion longitudinally of the housing between an exposed position extending at least partially outside the housing and an enclosed position within the housing. The housing includes an upper wall provided with a wedge-shaped tongue; sidewallsof the housing depending from the upper wall carry flanges adjacent their lower ends, defining a groove. The tongue on the upper wall of one container may be slid longitudinally into mating relation with the groove on the lower wall of an identical, other container so that the two containers may be locked together in vertical registry. Additional containers may be added by similar tongue-and-groove engagement to build up connected, vertical stacks of cassettecontainers. The containers thus connected create a file assembly for storage of the cassettes, occupying a 'minimum of space and providing enhanced protection and ease of finding for the cassettes.

DETAILED DESCRIPTION Referring to FIG. 1 of the drawings, an assembly 8 of cassette containers 10 each constructed in accordance with the preferred embodiment of the invention, is there shown.

Each cassette container 10, which is of generally boxlike shape having forward and rear ends 12 and 14, includes a housing 16 slidably receiving a drawer 18. Each housing 16 (FIGS. 2 and 4) includes a generally horizontal upper wall 20 and two laterally spaced, vertical sidewalls 21 extending downwardly from the upper wall. Fixedly secured to the sidewalls adjacent the lower ends thereof are two generally horizontal, inwardly facing narrow flanges 22. The previously mentioned drawer 18 rests on the upper surface of the flanges 22 of the housing 16, with vertical sidewalls 26 of the drawer in sliding contact with the interior surfaces of the sidewalls of the housing.

Projecting upwardly from the upper wall 20 of the housing therealong is a wedge-shaped tongue 28 having a flat horizontal upper surface 30 bounded by. two laterally spaced, wedge edge surfaces 32 inclined downwardly and inwardly. The flanges 22 of the housing define a groove 34 spaced below and generally coextensive with the wedge member 28. The edges of the groove 34 are bounded by groove edge surfaces 36 formed on the flanges 22 inclined downwardly and inwardly.

To assemble one container with another, one container is placed at a lower level than the other and the forward end of the tongue 28 on the lower container is slid into the open rear end of the groove 34 in the upper container. The lower container is then advanced forwardly beneath the upper container until it is in vertical alignment therewith, as which time further forward movement of the lower housing is restrained contact with a pair of inwardly projecting stops 35a secured to flanges 22. The stops 35a fit into correspondingly positioned notches 35b in the tongue.

In an important feature of the invention, the tongue 28 is laterally tapered so that the forward end of the tongue is less wide than the rearward end of the tongue (referring to FIG. 4 the dimension X is greater than the dimension Y). The groove 34 is correspondingly tapered to the tongue with the groove edges 36 parallel to the tongue edges 32. Moreover the width of the groove 34 is slightly less then that of the tongue so that on assembly with another container the groove edges are forced relatively apart, said flexing being permitted by the natural resilience of the housing material. As a result the groove edges 36 are biased against the engaged tongue 28 by the resilience of the flexed housing, thus providing a satisfactorily tight connection between the containers. Additionally the provision of tapered wedge-and-groove members reduces the need for accurate machining to provide a mating fit. Other advantages of the structure described are that the provision of an opening which extends entirely through and along the lower wall reduces the amount of material used in the housing, and also reduces the overall height of a stacked assembly of the containers to a minimum by effectively removing the lower wall thickness of each housing.

Adjacent the rear end of the housing extending transversely across the lower surface of the flanges 22 are two rounded, downwardly facing grooves 38 (FIG. 4) extending only partially into the thickness of the flanges. Aligned vertically above the grooves, projecting upwardly from the upper surface of the upper wall 20, are corresponding transverse ribs 40. As the upper container moves into the vertical alignment with the lower one, the natural resilience of the housing material enables the ribs 40 on the lower housing to snap into the grooves 38 on the upper housing. This arrangement retains the containers in connected relation against relative sliding motion during subsequent opening and closing of the container drawers.

It will be appreciated that the tongue-and-groove assembly described permits the containers to be readily stacked together'in'connected relation, thereby providing a file assembly for the cassettes from which the cassettes may be readily withdrawn by opening the respective drawers in which they are contained.

The housing 8 is desirably formed of a transparent rigid plastic, such as an acrylicplastic to permit the cassette within to be seen and to provide an attractive pack from a merchandising point of view. Adjacent the midpoint of the housing, two laterally spaced, hooklike lugs 42 are provided for supporting an information card (not shown) on which may be written the identity of the particular cassette contained in the container. To facilitate gripping the container when sliding it onto another container, two vertically ribbed finger grips 44 are provided on each of the two sidewalls 21 adjacent the rear ends thereof in a convenient location to be grasped by a persons fingers.

The previously mentioned drawer 18 (FIG. 3) includes a generally horizontal bottom wall 46, vertical forward and rear end walls 48 and 50 and the previously mentioned vertical sidewalls 26. When two containers are in engaged relation, the upper surface 30 of the tongue 28 of the lower container is disposed in flush horizontal relationship with the upper surface of the flanges 22 of the upper container so as to provide a continuous floor surface providing continuous underlying support for the drawer in the upper housing.

The bottom wall 46 of the drawer is provided with a vertically raised portion 52 having a cassettelike outline, to assist in locating the cassette in an appropriate position for withdrawal when the drawer is open. Extending upwardly from the raised portion 52 are two fixed lugs 54 for locating the cassette in place in the drawer. To facilitate lifting the cassette out of the drawer, finger openings 56 are provided in the sidewalls 26.

To assist opening of the drawer, laterally projecting vertically ribbed finger panels 58 are provided at the forward ends of the sidewalls 26. The outer side surfaces of the finger panels 58 are generally flush with the outer surfaces of the sidewalls 21 of the housing 16. Each finger panel 58, which is bounded by a rearwardly facing arcuate edge, is received within a correspondingly contoured opening 60 (FIG. 4) in the sidewalls ofthe housing.

Closing motion of the drawer within the housing is limited by contact of the edge of the finger panels 62 with the sidewalls of the housing, while inadvertent total removal of the drawer from the housing is restrained by contact of the rear wall 50 of the drawer with a pair of downwardly depending stops 62 secured to the underside of the upper wall of the' housing adjacent its forward end. detents open Another important feature of the invention resides in provision of structure whereby the drawer may be held against inadvertent opening while the container is in single condition yet permit free opening and closing motion once the container has been connected in a stack with other, identical containers. For this purpose the housing is provided with vertical raised projections 70 (FIG. 4) on the inner surface of the sidewalls 21 adjacent the forward end thereof. The projections 70 are snapped into aligned vertical grooves 72 (FIGS. 3 and extending partially into the thickness of the sidewalls 26 of the drawer, when the drawer is in its enclosed position within the housing and act as detents restraining movements of the drawer out of the housing. Such restraint is wanted when the container is in single condition to prevent the drawer accidentally falling open and dropping the cassette out when the container is picked up.

However, once the container is assembled with others into a stack, the possibility of the individual container being picked up in such manner as to permit accidental falling out is less likely and it would be desirable to cause the projections 70 released from the grooves 72 to permit free sliding of each drawer within its housing. As the tongue on one container housing is moved into the groove of another container housing, the previously described distortion of the housing of the upper container moves its sidewalls 24 laterally apart to a sufficient extent to move the projections 70 of the distorted housing out of the grooves 72 of the associated drawer thus freeing the latter for motion (as shown in dotted lines in FIG. 5).
